Definitions

  • OMPI r U.S. Patent No. 2,992,019 to M.D. MacArthur shows a casing joint having metal-to-metal sealing means responsive primarily to extremes of inside fluid pressure.
  • the dis ⁇ closed interior sealing for the pin and box provides a fourteen degree (14°) interior seal that is spaced a distance from the threaded inner connection to enable the deformation or strain on the pin, in response to the in ⁇ side fluid pressure, to flex the pin interior sealing sur ⁇ face against the box interior sealing surface and obtain a greater sealing force.
  • the sealing contact area decreases which increases the sealing force over the reduced area.
  • the distance between the pin and the seal surface remains the same while the center of the sealing area moves slightly toward the thread during such sealing flexing.
  • U.S. Patent No. 4,009.893 issued to Schatton, et al. discloses a tubing or casing joint with box and pin members having two axially spaced thread sections separated by a radial step zone which includes for the pin member, an annulus having an axial undercut.
  • the endface of the an- nulus bears against a complementary face in the step zone of the box member and serves to act as a complementary thread stopface, in addition to a stopface at the end of the pin member and in the box member.
  • Figure 2 illustrates an alternative embodiment of the invention with a longitudinal cross-section showing threads cut on a taper angle with respect to the axis of the male and female members of the joint;
  • Figure 1A illustrates that the load flank 44 on the thraads is at an angle ⁇ which is measured counter ⁇ clockwise from the vertical to the longitudinal plane of the threads.
  • mag ⁇ nitude of the negative thread flank angle or the angle of the reverse angle shoulder should not exceed thirty degrees (30°) .
  • magnitude of the angle of the conical sealing surfaces relative to the joint axis should not be greater than fifteen degrees (15°) .
  • dissimilarity of the angles of incline of the sealing surfaces of the male and female members should be less than one degree where the angle of incline of the member having the greater wall thickness should be greater than that of the member having the les- ser wall thickness.
